WHITFIELD HAINER, OF TORONTO, ONTARIO, CANADA.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Dee. `13, 1910.

Application led May 25, 1909. Serial No. 498,207.

To all `whom tt may concern;

Be it known that I, WHITFIELD HAINER, of the city of Toronto, in thecounty of York and Province of Ontario, Canada, have 1nvented certainnew and useful Improvements in Type-Writing Machines and I herebydeclare that the following 1s a full, clear, and exact description ofthe same.

vType writing machines for mamfoldmg purposes are now providedwith`auxiliary Icarriages from which the carbon and the paper for theoriginal and impression copies are intermittently fed in continuousstrips from the carbon and paper rolls to the platens of the maincarriages. In certain of these machines provision is made for thewithdrawal of the carbon from `between Vthe original and impressioncopies before thewritten part is severed from the unwritten part of thecontinuous strip or strips, but the means by which this Withdrawaliseffected have no provision for correctly and positively returning thefree end of the carbon toa fixed `zero position, a necessary provisionto prevent the carbon being severed with the paper or withdrawn from animpression position.

One of the features of the present inven tion relates to a means bywhich the free end of the carbon can be correctly returned to a fixedzero position preferably between the line of severance andthe placewhere the platen receives the impact of the type and this part of theinvention is carried out by providing the shaft of the carbon roll witha pinion meshing`with a spur wheel and revolving in one direction as thecarbon is intermittently fed to the platen by the spacing of the lines,and providing the spur wheel with a circumferentially adjustable armoperating an audible alarm when' the spur wheel has completed arevolution or a predetermined lpart of a revolution so that the spurwheel and pinion can then be turned in the opposite'direction for therewinding of the carbon until the reverse revolution of the spur wheelis arrested by the adjustable arm engaging a fixed stop. It 'isadvisable however, before the carbon can be withdrawn from between theoriginal land impression copies,`to provide for the removal of thepressure exerted against the paper by the feed roll and paper lingers,the removal of this pressure bein accomplished by the releasing lever,which when actuated to release the pressure of the feed whereby loosesheets, piled on a support forming part of the auxiliary carriage, may

be fed to the platen by a manually operated feeder, either unitedly withthe feeding of the paper strips or independently thereof.

The invention further relates to a means by which an impression copy maybe simultaneously made on an envelop of the name and address written onthe original copy, this means consisting ofa supplemental carbon rollmounted in the auxiliary carriage and from which the carbon is fedbetween the platen and the adjacent strip or'sheet/of paper andautomatically withdrawn therefrom when the address has been written.

For an understanding of the invention reference is to be had to thefollowing description and to the accompanying drawings in which- Figure1, is a perspective view of part of a type writing machine showing themain carriage, the auxiliary carriage and the arrangement of the carbonand paper rolls and the manner in which the carbon and paper are fed tothe platen of the main carriage. Fig. 2, is 'an end elevation of theconstruction shown in Fig. 1. Fig. 3, is an end elevation of the platenshowing the releasing lever and the means actuated by the releasinglever for removing the pressure of the feed roll and paper fingers fromthe paper. Fig. 4, is a perspective view ofthe envelop guide attached tothe main carriage. Fig. 5, isa perspective view of part of one of therolls u on which the carbon or paper is woun and Figs. 6 and 7, arediaammatic views showing the osition of t e envelop with respect to thep aten when being inserted, addressed and ejected.

Like characters of reference refer to like parts throughout thespecification and drawings.

In the specification the term carbon is used to desi ate carbon paper,carbon cloth, or an simi ar flexible material holding color in so utionor covered with a coating of the same, suitable for making an impressioncopy of the type written matter wrltten on an underlying sheet.

The strips of paper a and b are continuously fed -to the platen c fromthe rolls a b mounted in the auxiliary 'crriage cl,

vspur wheel h. The arm j permits of the p-in la being disengaged fromand renga'ged with the spur whee connected to and unitedly movable withthe main carriage e and mounted in the auxiliary carriage d is a carbonroll f, from which the carbon is fed between the paper strips a and b.'The shaft g of the carbon roll f extends beyond the auxiliary carriageand is provided with a pinion g meshing with the spur Wheel It mountedon a shaft or stud i journaled in the auxiliary carriage d. The shaft orstud 'i projects beyond the outer face of the spur wheel 71. and isprovided with a loosely mounted arm j having lateral movement withrelation to the slide face of the-spur wheel and rotary movement on theshaft or stud, and projecting from the arm j is a pin lc engaging withthe teeth of the ateral movement of the teeth and the rotary movement ofthe arm permits it to be positioned to engage between any selectedteeth. The engagement of the pin k with the teeth of the spur wheelcauses the arm to revolve unitedly with the latter so that durin therevolution of the spur wheel in one irection, the lug l projecting fromthe arm j will actuate', the striking mechanism m of the alarm bell o to.announce the completion of the strip of written matter.- The arm whenthe spur wheel is revolved in the opposite direction'engages with theprojecting end of the shaft g and arrests the revolution of the spurwheel. For convenience the alarm bell o and the striking mechanism m areadjustably connected to and supported by a curved band p attached to theauxiliary carriage adjacent to the sur wheel, the adjustment of thealarm be lpermitting the length of written matter `to` be varied.

In-the use of the device above described, the paper strips a and b arefed from the rolls aand 'b'. to the platen c with the carbon from thecarbon roll f between them. When the freeend of the carbon reaches thezero position indicated byl dottedline 2-2 (see Fig. 1) preferablylocated between the knife gand the place 3 where the platen receives theimpact of the type, the

arm j is moved laterally to disengage the pin lc from the teeth of thespur wheel. L and is then turned in the direction indicated by arrowuntil it engages with the shaft g, the latter forming a fixed stop toarrest the revolution of the arm in that direction, the pin /tbeing thenpermitted to rengage with the teeth of the spur wheel. The paper stripsa and b and the carbon are then intermittently advanced by the spacingof the lines, and the advancement of the carbon causes the revolution ofthe shaft g and the pinion l g. The pinion g meshing with the spur wheelh causes the latter to revolve in the opposite direction to thatindicated by arrow, and carry with it the pin k and the arm j until thelug Z of the "arm engages with the striking mechanism 'mf of the alarmbell, announcing the line where the strip or strips of Written matterare to be severed. The arm j and spur wheel 7b are then turned in thedirection indicated by arrow torewind the ,carbon on the roll f andwithdraw the carbon .from between. the ori 'nal and impression copiesuntil its free en is returned to the zero position 2 -2. The travel ofthe arm j and spur wheel h in the direction indicated by arrow isexactly the same as the travel of the arm and spur wheel in the oppositedirection, consequently the same quantity of carbon is rewound on thevroll f as isunwound from it by the advancement of the carbon'during thespacing of the lines. The free end of the carl bon is thus returned ateach operation of the arm y', to the same zero position which beingbelow the knife g ldoes not come within the line of severance when thewritten part is being removed from the unwritten 'lli part of the stripsa b, consequently no waste j of carbon can occur, vand the carbon isalways in position for use forl impression purposes. It is necessary, orat least it .is advisable, to have the length of written matter ofuniform size, and it is for this reasonA that tlfe bell is Vactuated bythe arm when the spur wheel has completed a revolution or apredetermined part of a revolution, the arm being advanced toward thebell by the revolution of the pinion g and spur wheel h caused bytheadvancement of the carbon during the spacing of the lines. To vary thelength of the written matter, the bell o is adjustable on the curvedband p, and isv provided with a clampr by means of which it canv belocked in any adjusted position thereon. Before the carbon can beconveniently returned to its zero yposition the pressurelof the feedroll s and paper fingers t from the paper should be released, and

' this release is effected in the usual way by the releasing lever u andlink o.

The paper fingers t are adjustably connected to a rod t supported byarms w rockable from the shaft `@a mounted in the main carriage e, oneof the arms 'w being prolvided with an adjustable lug 1/ engaged by theusual releasing lever'u when operated to remove the pressure of theusual feed roll against the paper. The actuation of the releasing leveru to release the feed roll raises the lug y, the arms fw and rod t therod t lifting the paper fingers t away from the platen so that theyAwill relea e their pressure against the paper. When` the feed roll andpaper fingers have been `I/noved out of contact with the paper, the armj is turned in the\direction indicated by arrow until it engagesthe'shaft g which arrests its movement in that direction. 'The free endof the carbon is then at the zero position,

vase

feed the loose sheets successively to the "platen, the disk engaging thetopmost sheet `only durin its rotation. l

The lauxi iary carriage d is providedV with brackets i. in which ismounted a shaft z" supporting the carbon holder j for envelop-addressing purposes. The carbon holder 1s of a cylindrical character,provided with a slot'k, immediately above the shaft. z" for the passageof the carbon.` Projecting from the carbon holder j', immediately belowthe slot c is a plate Z, over which the carbon j passes.

Io address an envelop, the paper for the original and impression copiesis advanced beyond the platen a distance substantially equal to thewidth of the envelop as shown in Fig. 6. The envelop is then lnsertedbetween the paper for the last impression copy and the laten and thecarbon for addressing t e envelop is inserted between the envelop andthe last impression copy. The revolution of the platen is then reverseduntil the paper and the envelop are restored to the position where theaddress is to be written, the reversal of the platen reversing with 1tthe envelop and the paper for the original and lmpression copies asshown in Fig. 7. The wrlting of the name and address on the `originalcopy causes an impression to be made upon the envelop by means of ythecarbon v`from the carbon holder j. The advancement of the original paperby the spacing of the lines causes a corresponding advancement of theenvelo and when the latter is clear of the platen t e carbon holder 7"turns by gravity and raises theplate Z', lifting the envelop and thecarbon for addressing the envelo into a position clear of the platen,and ho ds them in that position until removed from the Atype writing4the nature of the invention.

vlspring clizp B The carbon holder j is provided with a the plate andpreventing it bein unwound from 'the carbon roll within 51e carbonholder except when sufficient vstrain is ap'- lied for that urpose. Oneend of the caron holder y" 1s open to receive the roll of carbon and theslot c communicates with.

the o en end to lenable the carbon to be intro uced into the holder in apartly unrolled-condition. j

When the envelop is of a length that its end will project beyond thepaperstrips a b, the main carriage e may be provided with an envelopiide m such as shown in Fig. 4, and whic is attached to the maincarriage as shown in Fig. l, and holds the proj ecting end of theenvelop against the laten.

The s ool ends q for the aper rol s a b and cargon roll are provi edwith clips 1" which en age t e shafts s supporting the rolls a b and f,the clips r belng provided with set screws t by'which the cli s arelocked to the shafts so that the spoo ends will unitedl revolvetherewith when the paper or car on is being rewound upon the spoolsthrough the agency of the knobs u.
